Excel Viewer FAQ
Is my workbook uploaded?
No. It is read in your browser tab and never leaves your device.
Are formulas and formatting kept?
Values are read (a formula shows its last calculated result); formatting, merged cells, charts and macros are not shown. This is a data viewer, not a spreadsheet editor.
What if my sheet has a title above the table?
The first row is taken as the header when it looks like one. If a sheet starts with titles, open it in SQL with read_xlsx and a range, for example read_xlsx('file', range = 'A3:F500').
Can it open .xls files?
Yes, both the current .xlsx and the older .xls format.
